Abstract
A process for remotely fixing toxic dust, such as plutonium oxide, on the surfaces of a sealed cavity defining an airlock between two enclosures containing toxic material which are sealingly coupled to each other, so as to avoid contamination of the atmosphere upon uncoupling of the enclosures. The cavity is filled through an inlet zone with a solution of silicone grease in a solvent, such as freon, which is capable of wetting the surfaces of the cavity. The solvent is vaporized and evacuated from the cavity such that the silicone grease is deposited on the surfaces of the cavity to fix the toxic dust thereto.
